Abstract:
Many of the archaeological pottery objects excavated from the archaeological sites have suffered from different phenomena of deterioration. This kind of pottery needs a consolidation process for improving the physical and mechanical properties. Some archaeological pottery samples were obtained from the region of Tel pasta at Sharqia in the East of Delta, dating back to the Ptolemaic age. The pottery samples used in the study represent different models from the site for their use in Laboratory study. Scientific laboratory evaluation of some acrylic and silicon consolidation materials were done such as Monomer Poly Methyl Methacrylate, Paraloid B- 82, Ethyl Silicate Copolymer AS 21, a mixture of Ethyl Silicate Copolymer AS 21 and Paraloid B-82 and Tegovakon. Many experiments, tests and different examinations were done on The treated pottery samples such as determination of physical and mechanical properties, the examination of scanning electron microscope and thermal, light artificial ageing processes. Tests and experiments have all proved that one of two consolidants (First, a mixture of ethyl silicate copolymer AS21 and Paraloid B-82 at a rate of 1:1. Second, ethyl silicate copolymer AS21) must be used to consolidate archaeological pottery discovered from damp soil.
